CEMENT DERIVATIVE WITH SELF-SEALING CAPACITY

摘要

The present invention relates to a cement-derived material with self-repair capacity, i.e. self-sealing of the microcracks or microfissures that might appear in said cementitious material. To that end, microcapsules containing an epoxy-type resin within are synthesized and said microcapsules are incorporated into the cementitious matrix, which is hybridized with STOGA (amine), which emerges to the exterior when the microcrack ruptures the microcapsules, reacts with the STOGA (amine) material and seals the microcrack. Furthermore, STOGA confers improved mechanical properties on cement which has microcapsules with epoxy resin, which is less resistant than cement alone.
